Alejandra Herbert Mainero

POSTDOCTORAL RESEARCHER

Alejandra obtained her bachelor’s and MSc degrees in Biology from Universidad Autonoma de Queretaro in Mexico. She then moved to Scotland for a PhD in Evolutionary Biology with Sarah Reece at the University of Edinburgh. Alejandra is interested in understanding the evolution of malaria-causing parasites, and parasitology has been a common research topic throughout her career. To unravel parasites’ intricate lives, she uses interdisciplinary approaches and has used a wide variety of models, such as maternally transmitted gastric nematodes in sea lions and parasites that cause malaria.
